Soil is not the same as soil. There is soil on earth where allmost nothing can grow, because it is too salty, or lacking fertilzer. The research here is using flies for producing that fertilizer.
(but I think they still need to eat something else than mars soil)
So how is that a serious question, unless you want to involve me with academic pedantries?
"Please, how is "soil" different from "soil"?"
Like I said, differences in how fertilzed it is, so how much humus it contains. And what kind of humus, ph value, .. you know it.
The research here is basically using flies as fertilizers.
My question without reading any further is, where are getting the flies their food from? From outside the system probably and not from the soil. But maybe insects are still helpful, so good, that this student showed it, right? Why then nonsensical?
